Main Pcb Jumpers - Cardinal 205 Installation And Technical Manual

Main PCB Jumpers

J1 – BATTERY CHARGE MODE
Place jumper J1 in the Full position when operating the indicator totally from battery power and
only recharging the battery pack when it is low. Place jumper J1 in the Trickle position when
operating the indicator from commercial power and using the battery pack to supply power only
in the event of a power loss.
J2 – AUTO-ON JUMPER
The AUTO-ON jumper J2, when connected, will cause the indicator to power on automatically
whenever power is applied to the power input connector. If power is lost momentarily and then
reapplied, the indicator will turn on without pressing the ON key.
J3 – 8V EXCITATION JUMPER
The 8V EXCITATION jumper J3, when connected, sets the load cell excitation voltage to 8V
for operation with the 12 VDC battery. To operate from the 12 VDC battery, the load cell
excitation voltage MUST be set to 8 VDC (J3 closed). Battery operation with the load cell
excitation voltage set to 12V will result in an unstable weight display.
J4 AND J5 – SENSE JUMPERS
If the sense leads are NOT used, you must install plug-in jumpers at J4 and J5 adjacent to the
terminal block. These jumpers attach the sense leads to the excitation leads. If sense leads
ARE used (as in motor truck scales), these plug-in jumpers should be positioned on one plug-
in pin only or removed and stored for later use.
J10 – DEAD LOAD BOOST JUMPER
For very low dead loads (less than 10% of the combined load cell capacity) connect the dead
load boost jumper J10 on the printed circuit board.
J11 – 12V PWC SRC (SOURCE)
The J11 jumper, when connected (CLOSED) supplies 12 VDC @ 25mA from the 205 indicator
to a solid-state relay or other load of 200 ohms or greater. When J11 is OPEN (positioned on
one plug-in pin only or removed), the 12 to 24 VDC must be provided from an external source
to P10-6. The load must still be 200 ohms or greater.
Re-Installing The Rear Panel
After all terminations have been made, remove the excess cable from the indicator enclosure
and securely tighten each of the cable gland connectors. Do not over-tighten these connectors
but make certain they are snug. DO NOT USE TOOLS! Finger tighten only! Insure any
unused gland connectors are plugged.
1. Make certain no cables or wires are exposed between the main housing and rear panel and
then place the rear panel onto the main housing.
2. Secure with the 12 acorn nuts removed earlier. Follow a diagonal pattern when tightening
the acorn nuts.
3. If using a battery, slide the battery into the opening, until you feel resistance and the edge
of the battery is flush with the bottom of the indicator.
4. Replace the Battery Access Cover and install the three acorn nuts removed earlier,
securing the battery in place.
